How do you cancel something that was never scheduled?

I've worked in media and business for many years and share my views here to generate discussion and debate. I once leaned towards National politically and actually served on an electorate committee once, but the party lost its way and is still lost in the wilderness. Nearly voted Labour once when Roger Douglas was Minister of Finance. I could never see my way clear to voting for NZ First for many reasons but I'm far from committed to one party or one set of views. Years ago I supported Bob Jones and the New Zealand Party and a quest for change and I have voted for Act more than once. Today, politically I don't have a natural home - so I have an open mind.
